Fans have this strong belief that their faves are all super close and ready to stand up for each other that whenever anything bad happens - "Fuck the company, it is all their fault".
An even more better example would be VIXXxHongbin when the latter himself said on live streamed that he was told to leave by a member (Leo).
We also know that Pristin had very shitty relationship behind the scenes that Pledis basically gave up on them.
Honestly, for some idols it is just business. Not for all, I am sure there is true friendship there (all my faves ) but people should be more objective when it comes to things like this.
